txt file to string. trailing whitespace?

Im trying to write a function that reads a txt file that is a paragraph of text line by line and returns a single string that is all those lines combined. This is part of that function:

   while ~feof(ifstream)

      str = strcat( str , fgetl(ifstream) , ' ' )

   end

The lines in the txt file do not have trailing white space, but the returned string is supposed to... But adding the ' ' to the strcat() function seems to just be ignored by matlab.

Is there an easy way to fix this?

Thanks,

Please read the strcat documentation: it says explicitly the circumstances under which trailing spaces are discarded.

Use horzcat instead of strcat.

Your feof() code is also a bit wrong. Please read http://www.mathworks.com/matlabcentral/answers/22289-read-an-input-file-process-it-line-by-line
